DiMarzio says for D Sonic:
Our first heavy humbucker of the 21st century, the D Sonic™ is a high-output bridge humbucker
designed for the extended low end and heavy chords that dropped tuning delivers, with serious treble response for single-note solos and standard tuning. The D Sonic™ is more than just a one-sound pickup, too. In addition to the standard series humbucking sound, our patented design utilizes 4-conductor wiring to access two different single-coil sounds plus parallel humbucking mode, for three additional sounds that are distinctive and versatile.
Recommended For: Solid body guitars,
bridge position.
Tech Talk: Those of you familiar with DiMarzio® history will note the visual resemblance to our old MegaDrive™, but the design is completely different. Installation direction makes a noticeable difference in the sound, particularly with overdriven amps. With the solid bar toward the bridge, the sound is a little brighter and better-defined, and this is the direction we recommend for heavy strings and low tunings. With the adjustable polepieces toward the bridge, the sound is warmer and a touch louder, and we think this works best for standard tuning and more solo-oriented playing. Each coil has a unique tonal character, so the two split sounds are different, and parallel humbucking produces a third clean and bright sound.
